Performance evaluation of FR2-based IoT and AI applications using a Quad Port Multiple Input Multiple Output Antenna

Abstract

A four-port Multiple-Input-Multiple-Output (MIMO) antenna array with a rectangular slotted construction in the ground plane is utilized to improve the antenna's radiating capabilities. The suggested antenna features an FR4 substrate with 30x30 mm² measurements. The modeling and measurement results are found to be in good agreement. After that, a pattern is created and assessed. The highest peak gain of 5.03 dBi and performance characteristics of the suggested MIMO system make it suitable for deployment in 5G communication networks. The antenna's design has higher operating bands, an antenna array for greater gain, and a defined frequency range appropriate for 5G mm-wave communication. The radiation characteristics guarantee effective signal transmission and reception, resulting in increased network capacity and better user experience. Additionally, the use of an antenna array allows for beamforming, which enables targeted communication and reduces interference. With its robust design and excellent performance, the suggested MIMO system is poised to revolutionize 5G communication networks and meet the increasing demands of high-speed data transfer in the era of the Internet of Things (IoT) and connected devices.
